IMPORTANCE Scientific understanding of human voice production to date is a product of indirect investigations including animal models, cadaveric tissue study, or computational modeling. To our knowledge, direct experimentation of human voice production has previously not been possible owing to its invasive nature.

Previously, we have reported findings on the respiratory/phonatory subsystems. Speech recordings were made under three clinical conditions: before the surgery...
